It is possible to switch between welding with a solid wire and shielding gas, or welding with
self shielded cored wire without gas.

• Disconnect the welding power source from the mains
current supply.
• Open the side panel. Remove the protective cover.
• Rechuck the positive connection (+) and negative
connection (-) on the terminal block above the feed
mechanism.
• Reinstall the protective cover. Close the side panel.
• Move the return cable from the negative outlet (-) to the
positive outlet (+).
5.5 Wire feed pressure
Start by making sure that the wire moves smoothly through the wire guide. Then set the
pressure of the wire feeder's pressure rollers. It is important that the pressure is not too high.
Figure A Figure B
To check that the feed pressure is set correctly, you can feed out the wire against an
insulated object, e.g. a piece of wood.
When you hold the welding torch approx. 5 mm from the piece of wood (figure A) the feed
rollers should slip.
If you hold the welding torch approx. 50 mm from the piece of wood, the wire should be fed
out and bend (figure B).
